Ice cream in the blink of an eye — all thanks to science

Liquid nitrogen rapidly freezes the creamy ingredients with no cranking and no ice-and-rock salt mixtures.

“Instant ice cream” will be among the research projects presented by Everett Community College science and engineering students from 1 to 4 p.m. June 11 at Henry M. Jackson Conference Center, 2000 Tower St., Everett. Free.

In addition to liquid nitrogen ice cream, students will explain how they made science-y stuff like slime, a water bottle rocket and a 20-gallon tank of “Oobleck” (a goo inspired by a Dr. Seuss book).

Vote for their favorite project; the top five vote-getters win prizes.
